Three inquisitive out-of-the-box thinkers in Mrs. Greer's class - Rosie Revere, Iggy Peck, and Ada Twist- save the day during a class field trip by using their wits, engineering prowess, and problem-solving skills. This fun new musical is based on the book series by Andrea Beaty ("Rosie Revere, Engineer;" "Iggy Peck, Architect;" and "Ada Twist, Scientist").
